UIActionSheet mixed up with previous values

Question

I'm using UIActionSheet to be called from different UITextview. Once as date picker and as list of values.

The second time is called values will mixed up with previous values.

Could someone please help with this issue.

- (void)viewDidLoad
{
  pickerViewPopup = [[UIActionSheet alloc] initWithTitle:nil
                                              delegate:self
                                     cancelButtonTitle:nil
                                destructiveButtonTitle:nil
                                     otherButtonTitles:nil];
pickerView = [[UIDatePicker alloc] initWithFrame: CGRectMake(0, 44, 320, 266)];
catPickerView = [[UIPickerView alloc]initWithFrame:CGRectMake(0, 44, 320, 266)];

[super viewDidLoad];
}

You need remove previously added subview from your pickerViewPopup before adding new one:

...
[catPickerView removeFromSuperView];
[pickerViewPopup addSubview:pickerView];
...

and

...
[pickerView removeFromSuperView];
[pickerViewPopup addSubview:catPickerView];
...
